Great that you fixed it. If you solved it by removing printf, it could be some error with the uart functions, or with STDIO retarget functions.

Thank you for your reply.

It's solved. The error a 0x0004 was solved by changing baudrate, Ram size and Ram start.

After then, Error code 0x0001 (SRV_HANDLE....Error) was appeared.

I don't know exactly error cause but, It was solved by removing the printf function. Thanks.

The error you are receiving in the APP_UART callback, which is passed to the error handler, is not the same error codes as the global errors. The error code refer to the ERRORSRC register in the UART peripheral. 0x0004 means a FRAMING error is detected.

Hello, Jørgen Holmefjord.

I have changed both Ram Start and Ram Size. So, nrF_sdh_ble_enable error was solution.

But, Same Error (Error 0x0004 NO_MEM) was looped in the APP_UART_COMMUNICATION_ERROR : APP_ERROR_HANDLER (main.c 150)

This is Error code --> NRF_ERROR_NO_MEM (0x0004).

And main.c 409 --> err_code = nrf_sdh_ble_enable(&ram_start).

I have changed Ram Start but same issue was looped.

I think I did what I had to do. What should I configure?

I can't see any error codes in your last image, and in your first image the error seems to originate from the uart_handler, not the init function. Can you please provide the correct error code causing the application to end up in the error handler?

Hello there,

have you configured your sdk_config.h file?
